To all whom 2'25 may concern;

Be it known that. I, DANIEL. YOUNG, a citizen of. the United States,residing. in Brooklyn, in. the county of Kings and State of New York,have invented. certain new and useful Improvements in Apparatus forTreating and Forming Weighted. or Loaded. Sheet Fabrics, of which thefollowing. is a specification.

The objects of my invention or inventions herein disclosed are toprovide a. new and improved apparatus for treating sheet-fabrics, of'anyand all forms,.in wliichuin the course. of such treatment thefabricesheet is unroilediand' rerolled, and in its passage from feed. toreceiving or take-up. roll is supplied with any required impregnating,loading,

weighting or surfacing material, the proper amount of such: materialsupplied to the fabric-sheet,..of which,.it is necessary to determinefrom time to. time by. weighing the. same, until, the required grade of:the finished material has been reached by. the depositionv or,impregnation. of the fabric with the required quantity oftheimpregnating. or. loading material; and may be applied to sheets ofwoven or knitted fabrics,

leather,. etc..; paper of all forms including.

sensitized photographic papers, etc..; but. as

shown and described. herein my. said improved1 apparatus are thoseespecially adapted for the: water-proofing or. as it 1s commonly knowninthe' art, rubberlzmg of I woven sheet-fabrics.

My said improved apparatus is fully shown, described and claimed in thefol lowingv specification, of which the accom panying drawingforms a.part, wherein' similar. letters, or. numerals of referencedesignate likeor equivalent parts wherever found'throughout the several news, and 111which:

Figure 1 is a front end. view. in elevation.

of improved combined weighing and roll-shifting, apparatus, for carryingmy:

saidv method. into effect, in position ready to be operated;

Fig. 2 is a side view of such apparatus looking toward-the leftof;Fig,.1inthe direction of the arrow,.in position upon theroll-supporting mechanisms showing the roll' of fabric in positionthereon.

Referring to. the drawing The reference letter A,.. designates thefront. end of a fabric-sheet waterproofing or. rubberizing. machine of:an old andwell known. form, showing my improved combined roll-shiftingand. roll-weighing apparatus B attached thereto;v C designates thesteam-coil fabric-sheet supporting: and. drying. bed; D the combinedtrolley-carriage andweighing scale of B; E. the. combined lifting androll-swinging, shift frame;- and F, a roll of the sheet-fabric about.to. be. treated, in, position upon the. supportingshaft. I

In the treating or rubberizing machine, the reference numeral 11designates the knife-roll shaft, supporting and: rotating the knife-roll11, such shaft 11 being rotated tothe right as shown by the arrow. bythe pulley 12, connected. with a drivingpulley. l3v by a belt 12. Suchknife-roll 11 is sofcall'ed for the reason that just above it is locateda spreading-knife, which extends longitudinally thereof with just spaceenough between it and the peripheral. sur-' face of the roll, to permitthe. passage of the fabric-sheet H (shown in dotted lines) and therequired quantity of rubber or other impregnating material superposedthereon, the surplusbeing held back by such knife, whichwhile not shown,is adjusted to the proper height by the screw-shafts I operated by thehand wheels I, which shafts are attached to the knife at either end; Kdesignates the upper or feed-rollmechanism carrying the roll F, ofsheet-fabric H, about to be treated, from which roll the fabric H passesup over the knife-roll 11, just before it reaches the knife, being fedwith a sufficient quantity of the rubberv Or other treating material orfluid, usually delivered automatically from any suitable automaticfeeding-receptacle, the surplus being held back by the knife; and fromthe knife roll the top-ply of fabric H, passes over the drying bed C,usually of the steamcoil form shown, at the extreme end of which itpasses downward over an idler-roll (not shown), and the bottom-ply H,returns to the front, and is Wound up on the take-uproll L, all asclearly indicated in Fig. 2; the lengthzof the hot drying steam-coil bedbeing such that by the time the treated fabric has passed over it to theend-roll (not shown), the rubber, etc., will have been thoroughly dried.The feed-roll K, and take-up-roll L, are of identical construction,being at one period one, and then the other, and are each comprised of arectangular roll-shaft, 20, upon which is mounted a roll-sleeve 21,usually for the sake of light ness of wood, having a squarecentrallongitudinal bore to receive the shaft 20 so the shaft and sleeve willrotate in unison.

Axially mounted on, or connected with the shafts 20, at eitherend so asto rotate in unison therewith are wheels, which according to the variedpositions of the shafts, in the feeding or take-up positions ashereinafter described, serve either as drive or brake-wheels, accordingto the exigencies of their particular position at the moment. The rollshafts are supported in position upon the main-frame A of the machineupon supporting-brackets 15 and 15 respectively, formed integral withthe securing base-plate let, secured by bolts 31 to the front endside-pieces or flanges 80 of the mainframe A; which supporting-bracketsare provided at their outer ends with suitable journal-boxes P in whichsuch shafts 20 are revolubly supported. And in the forms offabric-treating apparatus hitherto used, upon which my apparatus is animprovement, the wheels 28, 28 and 29, 29 are secured to the outer endsof the shafts 20, which extend through such journalbones P, which areprovided on the upper sides or faces with slots (not shown), per mittingof such shafts, wheels, etc., being lifted out of such journal-boxes.And hit-herto in the operation of the machine this is done by two meneach taking hold of an end of the shaft and lifting the same clear, thelower take-up shaft L, carrying the finished roll of fabric F, (Fig. 3),after being taken out and placed upon a scale so as to determine theincrease in weight of the fabric, being then replaced in the upper andfeedroll journal-boxes of the brackets 15, while the empty feed-rollshaft of K, removed from such upper boxes is then placed in position inthe like journal-boxes of the lower-brackets 15, to act as a take-up orfinish roll. And in this shift, by the machines and processes heretoforeused, for the reason that there may be some difierences as to thethickness or quantity of the treating material fed to the two side edgesof the fabric being treated, in order that such discrepancies of feedingmay be overcome in order to make a smooth and perfect coating orimpregnation, etc., of the fabric (especially, when as in the highergrades of rubberized fabric). it is necessary to run the fabric a numberof times through the ma- --chine, sometimes as many as five or six, whenthe take-up roll is shifted into posimethod herein disclosed, described,and

claimed, by the form ofapparatus for carrying the same into effect, alsoof my 1nvention set forth herein, the brake and drive-wheels of theroll-shafts remain permanently in position in their journals, and

only the center removable fabric-holding wooden slip-sleeves 21, andshafts 20, constitutin the fabric-roll supporting por tions or suchshafts, are removed, thus greatly lessening the weight necessary to beshifted; and by my improved combined roll-shifting and weighingapparatus, I obviate the necessity of removing the roll to be weighedfrom the vicinity of the machine to a separate scale or weighingmechanism.

in my improved form of apparatus the combined drive and brakewheels 28,28, and 29, 29, instead of being secured upon the shafts 20 are securedin'any desired manner usually by means of cotter pins or set screws 22upon short studshafts 17, 17, and 19, 19. The wheels 28 and 29 beingrigidly secured upon the outer ends of the studshafts 17 and 19,formed'integral with the stud-shaft socket-heads 22, having at theirinner ends a square or rectangular orifice to receive the like shapedsecuring ends 22 of the roll-shafts 20, upon which are formed thecylindrical portions .23 for the securing thereto (as hereinafterdescribed), of the lifting releasable twin-hooks 52 secured to the endsof the two depending portions 51 and 51, comprising the lift-chains N.The stud-s1ipshafts 11 and 19 are each formed integral with a boss 27,against the outer face of which the pulleys 28 and 29 abut, which bossis provided with the journal inner portion or stud shaft sleeve P whichpasses through the journal-box in its particular bracket 15 or 15 and isprovided at the end with the central axial sliphollow 26, in which isslidingly held by means of the securing-pin 26 passing through the slot25, the rear cylindrical slip extension of the reciprocating studshaftsocket head 23; a coil-spring 24: being interposed between the end ofthe main portion of the stud-shaft and the socket head 23, normallyforcing such socket-head 23 out to the limit of the play of thesecuring-pin 26 in the slot 25, as clearly indicated in Fig. 8; andafter insertion in place in the bracket-journal, the stud-shaft sleeveor journal inner portion P is secured in fabricstrip becomes place by acollar 27 secured thereto by a set-screw, or in any other desiredmanner.

Secured above the brackets 15 and 15 usually and preferably parallelwith the axes of rotation of the shafts 20, is an overhead trolley-rail33 usually of the I-beam form shown, suitably supported in position,usually by being secured to the ceiling upon which travels thecarriage-yoke 3%, having the supporting traction-wheels 35, which yokesupports the main-bar 36 of the combined supporting trolley-carriage andweigh ing-scale D. Pivoted to a downward extension of the main-bar 35 bya pivot 36, is the vibrating scale-lever 37, the outer free end of whichvibrates up and down between the two lock-cam supporting yoke-pieces 28formed integral with the scale-lever 37, carrying at the lower end thelock-cam pivotshaft 41, vibrated by the lock-cam lever 39, and carryingthe lock-cam 39 shown in the vertical scale releasing. and unlockingposition, in Figs. 1 and 2.

Formed integral with or rigidly secured to the scale-lever 37 at itsouter free end adjacent to the lockcam 39, is the scale actuating-rod40, connected with the scaleplunger or vertically reciprocating-shaft 41by a pivot-bolt 42; the scale-mechanism and dial being indicated'by 43.Pivotally supported by the scale-lever 37 adjacent to the center, is thesupporting scale-hook as, carrying the roll swing-lift supportingchains45 and 45, the outer ends of which are hooked or otherwise firmlysecured to the end journal-box pieces 46 and 46 of the lift swing-frameE, formed integral with the cross bar 47 and central journal-box piece47', journaled-in which is the driveshaft 4:8, rotated through asprocketwheel 4c9,by an endless hand-chain 4:9, or by a power-pulley 50,driven by a belt. Also revolubly supported in lower journal-boxes formedin such pieces 4E6, i6, and 6L7, is the lift-chain shaft 55, upon theends of which are secured the lift-chain gear-wheels 56 and 56, meshingwith like smaller drive gear wheels 57, rigidly secured to the driveshaft 48; and secured upon the ends of the ilift-chain shaft 44:, arethe liftchain sprocket-wheels 5%,actuating the roll supporting-chains N,provided at their ends 51 and 51, with the twin-hooks 52, for supportingthe roll shaft 20 by being slipped over the cylindrical end portions 23thereof.

Formed integral with the journal-box piece 4L6, of the lift-swing-shaftE is a bar 61 formed integral with a housing 60, through the center ofwhich passes the drive-shaft 48,- which housing contains within it atwo-way reversible and releasable stop-pawl drive-shaft locking-device,and mechanism actuated and shifted by the shiftlever 62, whereby, by thethrowing of such lever 62 into the vertical position shown in Figs. 1and 2, the drive-shaft 48, and con-- sequently the shaft 55 will belocked against rotation, and when shifted to the horizontal in onedirection, will act as a stop-pawl against rotation in one direction,and when in the opposite direction, reversibly, whereby as the chain 49is operated such ratchet and pawl-mechanism will maintain the rollsbeing shifted at any desired height without danger of accidentaldisplacement.

In carrying out my improved method herein disclosed, and operating myimproved apparatus therefor, I take the following steps:

A roll of the fabric F yet untreated by my improved process mounted uponthe wooden axially rectangularly perforatedsleeve or mandrel 21, isslipped upon a rectangular feed-roll shaft 20, and the twinhooks 52 ofthe ends 51 of the chain N are thrown over the cylindrical lift portions23, of said shaft and by manipulation of the drive chain &9, and theconsequent rotation of the shafts t8 and 55, such fabric-roll andsupporting-shaft are lifted into the space between the feed-rollstudshafts l7 and 17; and the right hand rec tangular end 22 of 20,being thrust into the like-shaped stud-shaft socket of the reciprocatingstud-shaft-head 23, the shaft is thrust back into the socket 26,against, the tension of the spring 24:, and the right hand end of suchshaft 20 being brought into registry with the like socket of thestationary stud-shaft 22, it will be forced into the same by the tensionof the spring 24: and maintained in such position during rotation by thetension of such spring 24; or any suitable locking device (not shown)may be added to prevent accidental slipping of the roll-shaft. When soplaced in position, the end of the sheet of fabric forming the roll F ispassed up from the under side of the roll, over the knife roll 11, andbetween the same and the knife (not shown), and over the steam-coildrying-bed C, and after passing over the end roll (not shown) isthreaded back underneath the drying-bed O and secured to a like woodenslip-sleeve 21, mounted in like manner upon the finishroll ortake-upshaft 20, which has been placed in position in similarstud-shafts located in the journal-boxes of the lower outer journalbrackets 15. The manner of securing the end of the sheet to the takeupsleeve is immaterial and may be done by tacking, or any other desiredmanner; or even only by turning the take-up roll a number of times so asto wind several layers on the slip-sleeve 21. The take-up finish-roll Lis rotated by either the wheel 28 or 28, usually by 28, usually by meansof a belt O, (Fig. 1), driven from any suitable p0wer-supply source. Thefeed-roll wheels 29 and 29 are provided with suitable adjustable brakingmechanisms of any suitable form by which the fabric sheet is steadiedand lrept under tension in its passage through the machine.

The wheel 28 and talre-up-sha-ft 20 and sleeve 21 being put intorotation to the right in the direction of the arrow in 2, the fabric isdrawn off from the feed-roll and as it passes over the knife-roll 11,the fabric at the knife-roll is suppiied by hand or by anautomatic-feeding-device, (not shown), with the required quantity of theimpregnating or surfacing material to be deposited in or on such fabric,the surplus being removed by the knife (not shown), located above suchknife-roll hereinbefore referred to; and being thoroughly dried in itspassage through the machine upon, over and along the steamcoildrying-bed G, is wound up on the takeup roll L; and l efore the last endis allowed to pass over the knife-wheel, a threadcr leadsheetof othermaterial is attached to such end in the manner well known in the art,and such lead-sheet left in the machine to act as a leader for theinsertion of the same or another sheet, and when the front end of thelead-sheet is wound three or four times around the take-up-roll, thetake-up-roll is reversed in rotation and the threader leadsheetseparated from the treated fabric, thus preventing the labor and timethat would be taken, in threading the fabric sheet by hand through themachine upon the continuation of the operation.

The combined weighing and liftswing mechanism B carried by thetrolley-carriage D, is then moved into position and the chains N havinghad their ends 51 secured to the empty-feed roll-shaft 20 at K by theplacing of the twin-hooks 52 upon the cylindrical portions 23 of suchshaft, as clearly indicated in Fig, 1, while the filled take-up andfinish-roll carrying the treated fabric-roll F,

is secured in like manner to the ends 51, by.

he twin-hooks 52. The lock cam 39 is then by the movement of thelock-cam lever 39 to the horizontal-vertical and toward the right ofFig. 1, thrown into upward locking position so as to lock the scale-bar37 against downward movement, thus rendering the scale-mechanisminoperative, whereupon, by rotation of the drive-shaft 28, thelift-shaft 55 is (after the removal of the shafts 20 from theirrespective stud-shafts) rotated so that the roll shafts are reversed asto vertical position; and also swung horizontally a half turn upon thepivot-hook ri, to bring about end for end reversal of the rolls, whenthey are again inserted in place in the studshafts by which operationthe rotation of the feed-roll K will be reversed; that is if the fabricsheet H has been first fed from the under-side of the feed-roll K, asindicated in Fig. 1 this reversalwill cause it tobe fed from the top soas to bring what was the under and races-r3 untreated side of thefabric-sheet uppermost, and in position to be itself treated, in themanner hereinbefore set forth. In some cases, and when only one side ofthe fabric is to be treated or coated, there is of necessity no suchhorizontal swinging of the rolls. During this swinging operation thelock chains having the securing-hook 53 one of which is secured to themiddle of the endportions 51 of the lift chain l having been hooked intothe end 51 of such on either side as indicated in dotted lines at 53 ofFig. 2,

which will prevent swinging apart of the rolls during the swingingreversal; while the rolls are, upon unhooking of such chains maintainedin any desired vertical position by proper manipulation of the pawl andratchet shift-lever 62. in position, (usually when the rolls are inquarter turn position) the lever 39, is thrown down in to the verticalposition shown in 1 and 2,. so as to unlock the scalelever 37, when theweight of the finish-roll, of the two-rolls and the fabric, and theswing shift-mechanism will be indicated upon the scale-dial 43; and thetare of the supporting mechanism, and the weight of the fabric and itssquare-yardage surface being known, this weighing between each passagethrough the machine, by a simple math" ematical computation, will atonce determine, when the required grade of treated fabric has beenreached, whereupon the finished-roll of fabric F is removed, and a newand untreated roll inserted for like treatment.

it is evident that many changes and modiiications in my improved methodof fabric treatment, and also in the construction, arrangement andcombination of the several elements of my improved apparatus forcarrying the same into efiect, herein disclosed, may be made withoutdeparting from the scope of my invention, and I do not intend to limitmyself to the exact construction of apparatus, nor to all steps, nor tothe exact sequence of steps herein disclosed, shown and described.
